Census
Sienna in the 2020 Census
The 2020 Census recorded 25,547 people with the first name Sienna, which placed it at #1,383 in the published first-name tables. This is a snapshot of people who already had the name at the time of the Census.
The SSA sections elsewhere on this page answer a different question: how often parents gave the name to babies over time. The "people living today" figure on this page is different again: it is a current estimate built from SSA birth records and age-based survival rates, so the two numbers are not expected to match exactly.

Demographics
Ancestry and ethnicity for Sienna
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Sienna is White at 57.7%. The next largest groups are Hispanic (24.1%) and Two or More Races (9.3%). These figures describe the people who had the name in 2020, not any inherent property of the name itself.
The bar chart below shows how people with the first name Sienna described their own race and ethnicity on the 2020 Census form. The Census Bureau groups responses into six broad categories: White, Black or African American, Hispanic or Latino, Asian and Pacific Islander, American Indian and Alaska Native, and Two or More Races. When a category has too few respondents for a given name, the Bureau suppresses the figure to protect individual privacy, which is why some names show fewer than six slices.
Percentages are shown so the breakdown is easy to read across every published category. Because the 2020 Census first-name file also includes raw headcounts for each group, Name Census can show those alongside the percentages in the legend and hover tooltip.
Keep in mind that these are self-reported numbers. A first name does not determine a person's race or ethnicity, and the distribution you see here reflects the specific population who happened to carry the name Sienna at the time of the 2020 Census, not any inherent property of the name itself.

Origin
Meaning and history of Sienna
The name Sienna has its roots in the Italian language and culture. It is derived from the Italian word "siena," which refers to the city of Siena located in the Tuscany region of central Italy. The city itself was named after an ancient Etruscan settlement called "Saina."
Sienna gained popularity as a given name due to the rich history and cultural significance of the city of Siena. The city is renowned for its Gothic architecture, medieval cityscape, and the famous Palio di Siena horse race held twice a year. The name Sienna evokes a sense of warmth, earthy tones, and the vibrant terracotta hues associated with the buildings and landscapes of Tuscany.
One of the earliest recorded instances of the name Sienna dates back to the 16th century. In 1554, Sienna Santi was an Italian noblewoman who was a member of the prominent Santi family in Siena. She was known for her philanthropic work and support of the arts.
Another notable figure named Sienna was Sienna Miller, an American-born English actress, model, and fashion designer. Born in 1981, she rose to fame in the early 2000s with roles in films such as "Alfie," "Layer Cake," and "Factory Girl." She continues to work in both film and television.
In the world of sports, Sienna Fernandez was a Spanish tennis player who competed professionally in the 1990s and early 2000s. She achieved a career-high ranking of No. 27 in the world and won two WTA singles titles during her career.
Sienna Guillory is a British actress and former model, born in 1975. She is best known for her roles in the "Resident Evil" film series, where she portrayed the character Jill Valentine. She has also appeared in other notable films such as "Love Actually" and "Inkheart."
Sienna Williams was a British author and poet who lived from 1888 to 1961. She was part of the Bloomsbury Group, a collective of writers, intellectuals, and artists in the early 20th century. Her poetry often explored themes of nature, love, and the human experience.
While the name Sienna has its origins in Italian culture, it has gained popularity and recognition across various parts of the world, transcending its linguistic and geographic boundaries.

FAQ
Sienna: questions and answers
How many people in the U.S. are named Sienna?
Name Census puts the figure at roughly 36,821 living Americans. We arrive at this by taking every SSA birth registration for Sienna going back to 1880 and adjusting each cohort for expected survival using CDC actuarial life tables. The result is an age-weighted living-bearer count, not a raw birth total. That works out to about 1 in 9,309 US residents.
Is Sienna a common name?
We classify Sienna as "Uncommon". It ranks above 99% of all first names in the SSA dataset by living bearers. Across the full history of the data, 37,217 babies have been registered with this name.
When was Sienna most popular?
The single biggest year for Sienna was 2024, when 2,113 babies received the name. The fact that the average living Sienna is about 13 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
How common was Sienna in the 2020 Census?
The published 2020 Census first-name tables recorded 25,547 people with the name Sienna, or 8.46 per 100,000 residents. That placed it at #1,383 in the national Census ranking for first names.
Why is the Census count different from the living estimate?
Because they measure different things. The Census figure is a count of people who had the name Sienna in 2020. The living estimate aims to answer a current question instead: how many people with the name are alive today, based on SSA birth records and age-based survival rates. Since one number is a 2020 snapshot and the other is a present-day estimate, they are not expected to be identical.
What does the Census say about the gender split for Sienna?
In the 2020 Census sex table, Sienna appears almost entirely female. Of the 25,552 people counted with this name, 99.9% were female and only a very small share were male. The Census view is a snapshot of people living with the name in 2020, while the SSA section above tracks births across time.
What does the Census say about the background of people named Sienna?
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Sienna is White at 57.7%. The next largest groups are Hispanic (24.1%) and Two or More Races (9.3%). These figures describe the people who had the name in 2020, not any inherent property of the name itself. The percentages in the chart above come from self-reported race and Hispanic-origin responses in the 2020 Census.
Which group reports the name Sienna most often in the Census?
White is the largest reported group for people named Sienna in the 2020 Census, accounting for 57.7% (14,732 people in the published table).
Why can the Census sex total and race total differ slightly?
The Census Bureau published separate 2020 tables for sex and for race/Hispanic origin, and the released figures can differ slightly because of privacy protection in the public files. That is why this page treats the gender section and the race/origin section as two related snapshots instead of forcing them into one identical total.
Does every first name have Census demographic data?
No. The public Census first-name release only includes names that met the Bureau's publication rules, so many rarer names in the SSA files have no Census demographic snapshot. When that happens, the SSA trend, gender history, and state sections still appear, but the 2020 Census demographic sections are omitted.
What does the SSA popularity chart show?
The chart tracks births, not the number of people alive with the name today. Each point shows how many babies were given the name Sienna in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Sienna a female name?
Yes, 100.0% of people registered as Sienna in the SSA data are female. You can see the full per-sex comparison in the gender distribution section above, which includes the latest year rank, birth count, and peak year for each sex.
Is Sienna still being used today?
Yes. The SSA still recorded Sienna in 2024, and the page above shows its latest-year rank where available. A name can be well past its peak and still remain in steady use, especially if it built up a large population over earlier decades.
Why can a name have a lot of living bearers even if it is not trendy now?
Because living-bearer counts and current baby-name popularity measure different things. A name like Sienna can build up a very large population over many decades, even if fewer parents are choosing it now than they did at its peak.
Where does this data come from?
First-name figures come from the Social Security Administration's national baby name files, which cover every name on a birth certificate from 1880 to 2024. Living-bearer estimates layer in CDC actuarial life tables broken out by sex to account for mortality. The population baseline (342,754,338) is the Census Bureau's latest national estimate.
